it seems a lot of youtubers forgot about this game such as blitzgriegsler and baronvonletsplay...which isn't very good.anyways,i have suggestions:
kamikazer (duel wields fire grenades and runs into an enemy and blows up)
huge fire cart (double the size of a regular fire cart and needs 2 people to push it and has double the explosion size)
lancer (a soldier who has a lance and can have light armour,and the other 2)
if you want to add ships and a new map:
ocean map (you could put ships in the ocean map and when a ship dies,it sinks)sloop (a very light ship that has 6 cannons,3 on the side and 3 on the other side)
brig (a light ship that has 16 cannons,7 on one side and seven on the other with 2 cannons on the front)
frigate (a medium ship that has 24 cannons,10 on one side and 10 on the other with 4 cannons in the front)
men o war ( a heavy ship that has 44 cannons,20 on one side and 20 on the other with 4 cannons in the front)
there could also be different types of shots too:
regular shot (just a regular cannon ball that's ok against everything)
grape shot (good against light and very light ships,but terrible against medium and heavy ships)
the cannonball that is attached by a chain that goes to another cannonball (I forget what its called,but its good against sails which slow down the enemy ship)
heavy shot (very good against medium and heavy ships,but aren't very good against light and very light ships because the heavy shot is slow moving and light and very light ships are fast)
Idk if these shots/ships are accurate since I'm getting most of my information from assasins creed 4 black flag,but I think it would be cool to see ships fighting eachother :D and also I just noticed that the comments are fixed! fresh...................vanilla coke for everyone!
